HYDROCARBON-BURNER.

Specification of Letters Patent. I

Patented Sept. 10, 1912.

Application filed April 22, 1912.. Serial No. 692,422.

To all whom it may concern:

. Be it known that we, WILLIAM HUM- PI-IREY and THOMAS R. STEWART, citizens of the United States, residing at Auburn, in

the county of Nemaha and State of Ne Another object is to provide a burner ofthis character which will be simple, strong, durable and inexpensive in construction, eflicient and reliable in operation, and which may be readily applied to any form of stove.

With these and other objects in View, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings; Figure 1 is a vertical sectional view through a heating stove showing my invention. applied thereto; Fig. 2 is a perspective view of the burner removed from the stove; Fig. 3 is a central vertical longitudinal section of the same; Fig. 4 is a vertical cross section taken on the line l -4 of Fig. 3; Fig. 5 is a similar view taken on the line 5-5 of Fig. 3.

Our improved burner comprises a rectangular oblong shaped hollow body 1 which may be constructed of sheet or of cast metal and which is open on its lower side and has on its upper side a gas generating chamber 2 which corresponds in shape to the body of the burner and is flat and comparatively shallow as shown.

The body 1 of the burner has arranged therein near one end vertical transversely disposed partitions 3 and 1 which divide this end into a plurality of air chambers or compartments 5 and 6. Near the opposite end of the body 1 is a vertical transversely disposed partition 7 which forms in this end of the body an air chamber 8. The side walls of the air chambers have formed therein air holes or ventilating passages 9. The sides of the body 1 between the compartments or chambers 6 and 8 are slitted adjacent to the inner walls of the compartments and the slitted portions 10 of the sides are bent outwardly at their lower ends to permit the escape of the flames from the burner as will be hereinafter more fully described.

Arranged in the air chamber 5 is an oil feeding pipe 11 the upper end of which is connected with this end of the generating chamber. The lower end of pipe 11 terminates just below the burner and to said end is connected a fuel supply pipe 12 which extends out through the side of the stove and is connected with an oil tank or reservoir 13 or to any other source of fuel supply. The pipe 12 has arranged therein a cutoff valve 14: whereby the flow of oil to the burner is controlled.

In the chamber 8 at the opposite end of the burner body is a short gas conducting pipe 15 one end of which extends through the partition 7 into the central compartment of the body. The end of the pipe 15 in the compartment 8 turns up and is connected with this end of the generating chamber as shown at 16. The end of the pipe 15 which projects into the central compartment of the body is turned upwardly or provided with an elbow 17 the outer upper end of which terminates immediately below the bottom of the generating chamber at which point the gas is discharged and lighted.

When arranged for use the burner is placed on the grate or on the bottom of the stove as shown in Fig. 1 of the drawings. To start the burner the valve 14 in the pipe 12 is turned on and oil permitted to flow through the generating chamber and out through the gas conducting pipe 15 from the upwardly turned end of which it is dis-- charged and ignited. The burning oil from the pipe 15 rapidly heats the generating chamber 2 very hot, so that owing to the flat shallow shape of this chamber the oil passing therethrough is quickly converted into gas which is discharged from and burns at the upwardly turned end of the gas con ducting pipe 15. The burning of the gas beneath the generating chamber will keep the same heated so that gas is continuously formed from the oil passing through the generator. The flame from the burning gas is deflected by the bottom of the generating chamber out through the openings formed by the slitted outwardly bent sides of the generating chamber and into the stove thus rapidly heating the same and by providing the air chambers in the body of the burner as herein shown and described, air is permitted to freely circulate in the body thus mixing with and insuring a perfect combus tion of the gas.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construct-ion may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention, as defined in the appended claim.

Having thus described our invention, what we claim is:

A hydrocarbon burner comprising a hollow body having therein air chambers provided with air holes and having its sides slitted and turned outwardly between said air chambers, a fiat, shallow gas generating chamber arranged over and forming the top of said burner body, an oil supply pipe connected with one end of said generating chamber, and a gas conducting pipe connected with the opposite end thereof having its free end terminating and turned up be neath said generating chamber at which point the gas is discharged and burned.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
